Simulation of Multifluid Multiphase Flows with AUSM+-up Scheme

Abstract

An accurate and robust method is proposed for the simulation of two dimensional compressible multifluid flows. Our method incorporates the AUSM(+)-up scheme and the stratified flow model to discretize compressible single-pressure multifluid equations. This method satisfies the pressure-undisturbed condition and can capture the moving discontinuities accurately. It's also able to compute a very strong shock wave propagating across the gas-liquid interface. Two test problems, including the shock-bubble interaction problem and the shock-water column interaction problem, will be demonstrated in this paper.
